Porto star Hulk has opened the door to him leaving this summer. The Brazil international is a top target for Chelsea, while Manchester City and PSG have also been mentioned by representatives in recent weeks.

"If I am to change, undoubtedly it will be a good move," he tweeted last night. "I'll have to go to one of the big leagues, I'll do it with joy."

While his contract carries a €100 million buyout clause, agents have been informed Porto are now softening their stance and are prepared to consider offers for around half that figure.
